Tire inserts are one of the most critical aspects of Short Course off-road racing. Racers have asked JConcepts for a firmer and more durable insert and after much deliberation the JConcepts Profiled insert is ready. Having the insert with proper density for track conditions pays dividends to the racer and especially toward the end of races. Starting on too firm an insert, the driver feels “on edge” during the first run or subsequent runs on a set of inserts. Starting on too soft an insert, the driver’s vehicle is not responsive enough or runs the risk of too much insert breakdown during the tail end of a tires life which creates a squirmy or inconsistent feel. Having the feel that is just right requires a bit of balance of durability and hardness. To add to the construction and performance, JConcepts has added cut / grooves into the profile of the inserts to add an even greater driver to track feel. JConcepts is just right and always on target with the Profiled insert.
